OK, then maybe the MS people have fixed this meanwhile.
Anyways, I've now looked at the TrueType bytecode of the `aring' glyph
in DejaVuSansMono-Bold.ttf font (v2.34), and it confirms my guess: At
12ppem (this is 9pt at 96dpi), the bytecode moves the `ring' subglyph
up one pixel so that the top pixel row is outside the range spanned up
by usWin{Ascent,Descent}.
For the sake of compatibility with Windows, I recommend that the
DejaVu people slightly increase `usWinAscent'.
Please forward this to the DejaVu bug tracker :-)
